Abstract:
A method including evaluating a number of constituent precoders to be used in providing a single precoder to include in an explicit channel state information (CSI) report, to be transmitted from a user terminal to at least one device in a network, and combining the constituent precoders to form the single precoder in response to a determination that the number of constituent precoders to be used in providing the single precoder is greater than one. The method includes configuring to signal to transmit the explicit CSI report including the single precoder from the user terminal to the at least one device in the network.
